Aria

🎥 Project walkthrough: http://tiny.cc/arvoice

Aria answers the phone and runs a complete B2B sales call out loud, in real time.

She quotes real prices from a knowledge base, handles objections mid-sentence, negotiates an authorised discount, books a meeting, sends the invite, and pulls in a human only when she genuinely needs one.

The part worth watching

Open the console and a CRM lead page side by side.

Say:

“Actually, make that fifty devices.”

The record updates itself — no refresh.

That's not a mock. EspoCRM is the real system of record, including its audit trail of the agent working on the lead.

Under the hood

Agora's Conversational AI Engine handles the hard real-time audio — speech recognition, barge-in, and speech synthesis — and calls our FastAPI backend once per turn.

The salesperson lives in that backend:

• 🧠 10-tool reasoning loop

• 📚 Grounded retrieval over product docs

• 💰 3-layer negotiation stack

• 🤝 A separate deal-desk agent proposes discounts

• 🔒 Deterministic code decides what's actually allowed

She never talks past the walk-away floor, because that limit lives in code — not a prompt.

🇮🇳 Built for real conversations

She speaks English, Hindi, and Hinglish — the kind of Hinglish you actually hear in an Indian office.

When the caller changes language, her voice changes with them.
